What should I tell ER staff about my endometriosis?

If you’re in the ER with pelvic or abdominal pain and you have endometriosis (or strong suspicion of it), lead with the facts that help them triage safely: your diagnosis status (surgically confirmed vs suspected), any prior operative and pathology findings, and whether you’ve had complications like bowel, bladder, appendix, or diaphragm/thoracic involvement. Tell them what today’s pain is doing differently from your baseline—sudden onset, one-sided or right-lower-quadrant pain, fever, vomiting, fainting, heavy bleeding, chest/shoulder pain, or shortness of breath—and whether it seems cyclical or tied to your period. ER teams are trained to rule out emergencies first, so describing “what changed” and “what worries you most” helps them move faster and document the right differentials.


It also helps to be very specific about your symptom pattern and functional impact rather than just saying “endo flare.” For example: pain with urination or bladder filling, pain with bowel movements, constipation/diarrhea flares, rectal pressure, deep pain with sex, or pain that radiates to the back/leg—especially if those symptoms have a clear cycle pattern. If you have records, bring or show the most useful ones: operative reports, pathology reports, and recent imaging reports (and images if you have them). Those details can prevent your history from being minimized just because a CT or ultrasound looks “normal.”


After the urgent issue is addressed, many patients still need a clearer plan for the underlying driver of recurrent ER-level pain. Our team can review your records, make your history “clinically legible,” and discuss whether specialized evaluation and excision surgery may be appropriate—especially if you’ve been dismissed, have persistent symptoms despite prior treatment, or suspect deeper or multi-organ disease.

Go to the ER prepared

If ER visits haven’t addressed your endometriosis pain, our specialists can help you document your history, prior surgeries, and red-flag symptoms so you’re triaged safely. We can also evaluate next-step treatment options—especially when care has failed or symptoms keep escalating.
